Definitions

  • This invention relates to a multipot type disk brake having a plurality of pistons to press at least one of a pair of opposed friction pads.
  • Multipot type disk brakes are disclosed e.g. in unexamined Japanese patent publications 5-293626 and 9-177843. Such brakes have a brake fluid supply passage defined by a pipe casted in the caliper.
  • Such disk brakes have merits that no machining is needed to form the fluid passage, that greater freedom of layout of the fluid passage is obtained (which makes it possible to reduce the resistance to the flow through the passage and thus provide smooth flow of brake fluid), and that it is possible to reduce the wall thickness, weight and size of the caliper by reinforcing the caliper with the pipe.
  • Multipot type disk brakes include a caliper having a plurality of cylinder bores, and pistons each inserted in the respective cylinder bores for pressing at least one of a pair of opposed friction pads.
  • the other friction pad is pressed i) by an outer claw of the caliper (with floating type disk brake), ii) by a single piston, or iii) by a plurality of pistons (with opposed-piston type disk brakes).
  • the fluid passage in the caliper is defined by a pipe casted in the caliper through which the cylinder bores communicate with each other
  • the pipe is provided behind the cylinder bores and brake fluid is supplied to the cylinder bores through holes extending from the pipe to the respective cylinder bores
  • the thickness from the bottoms of the cylinder bores to the outer surface of the caliper tends to be large, thus unduly increasing the thickness of the caliper.
  • arranging a pipe 3 across the cylinder bores 2 has been proposed.
  • the pipe 3a may shift longitudinally in the hole 4. In the worst case, the pipe may come out of the hole 4, dropping into the cylinder bore 2 at one or the other side therof.
  • An object of this invention is to prevent shift and dropout of a pipe casted in the caliper in a simple manner.
  • a multipot type disk brake which has an opposed pair of friction pads and a plurality of pistons and at least one of the friction pads is pressed into frictional contact with a disk rotor by the pistons, a caliper formed with cylinder bores parallel to each other, the pistons being mounted in the respective cylinder bores, the cylinder bores communicating with each other through a fluid passage formed in the caliper, and wherein the fluid passage is defined by a pipe casted in the caliper so as to extend between the cylinder bores and communicate the cylinder bores with each other,
  • the pipe has a projection or recess in a diametric direction so as to closely engage with the caliper.
  • the pipe has cutouts so as to be disposed at bottoms of the cylinder bores.
  • the cutouts of the pipe should be retracted from the inner wall of the cylinder bore.
  • the engaging portions provided on the pipe can be formed by casting in the caliper a pipe having a projection or a recess on or in the outer periphery of the pipe.
  • the engaging portions provided on the pipe engage the pipe with the caliper each other, preventing longitudinal shift of the pipe.
  • the pipe shifts slightly due e.g. to weak bonding between the caliper and the pipe, the pipe will not come out or drop out of the hole formed by the pipe.
  • FIG. 1 is a horizontal sectional view of a disk brake embodying this invention
  • FIG. 2 is a partial enlarged sectional view of the embodiment of FIG. 1;
  • FIG. 3 is a partial sectional view of another embodiment.
  • FIG. 4 is a partial sectional view of a still another embodiment.
  • FIG. 5 is a similar view of a prior art disk brake.
  • FIG. 1 shows a disk brake embodying this invention, which is an opposed-piston type disk brake.
  • This disk brake includes a caliper 1, which comprises inner and outer calipers 1a and 1b separately formed of aluminum alloy or cast iron and coupled together by bolts (not shown).
  • the inner and outer calipers 1a and 1b are formed with a plurality of (two in the embodiment) cylinder bores 2 arranged parallel to each other.
  • a piston 5 is inserted in each cylinder bore 2 to press a pair of opposed friction pads 6 into frictional contact with both sides of a disk rotor D.
  • piston seals 7 having the function of retracting the pistons 5, pad pins 8 axially (with respect to the disk) slidably supporting the friction pads 6, fluid seals 9 provided at the connecting portions between a pipe 3 in the inner caliper 1a and a pipe 3 in the outer caliper 1b.
  • the pad pins 8 are supported by the calipers with its both ends inserted through pin holes (not shown) formed in the inner and outer calipers 1a, 1b.
  • the pipes 3 as a fluid passage are casted in the inner and outer calipers 1a and 1b.
  • the calipers are casted with the pipes 3 put in position.
  • the cylinder bores 2 communicate with a brake fluid supply port 10.
  • Each pipe 3 includes an intermediate short pipe 3a separated from the remaining pipe portion.
  • the parallelly arranged cylinder bores 2 communicate with each other through the pipe 3a provided therebetween.
  • the pipe 3a has a projection or bend 11 at its intermediate portion as shown on an enlarged scale in FIG. 2.
  • an engaging portion extending in a diametric direction of the pipe is formed between the pipe 3a and the inner caliper 1a (and outer caliper 1b). This portion prevents longitudinal shift of the pipe 3a.
  • FIG. 3 shows another embodiment in which the pipe 3a has a recess 12.
  • an engaging portion extending in a diametric direction of the pipe 3 is formed on the pipe 3a. These portions prevent longitudinal shift of the pipe 3a.
  • the recess 12 shown in FIG. 3 is formed by drawing the pipe 3a at its mid-portion. But such a recess or a projection may be formed in any other manner.
  • FIG. 4 shows another embodiment of a disk brake in which a pipe 3 extends across the bottoms of the cylinder bores 2.
  • the pipe 3 has bent portions 15 at both ends, and a middle straight portion formed with cutouts 14 which are in the cylinder bore 2 at their bottom.
  • the passage in the pipe 3 thus communicates with the cylinder bores 2 through the holes defined by the cutouts 14.
  • the bent portions 15 (refer also to FIG. 1) engage the inner caliper 1a (and outer caliper 1b), thus keeping the pipe 3 in position. Since the pipe 3 partially penetrates into the cylinder bores 2 so as to extend across the cylinder bores 2, it is possible to reduce the thickness t of the caliper bottom by the length a by which the pipe 3 penetrates into the cylinder bores 2, compared with conventional brakes of this type.
  • cutouts 14 of the pipe 3 are retracted from the inner walls of the cylinder bores 2 by forming recesses 13 to prevent the edges of the cutouts 14 from protruding into the cylinder bores 2 and interfering with the sliding pistons.
  • edges of the cutouts 14 are retracted only slightly.
  • the edges of the cutouts may be retracted not by recessing but by any other method such as partial machining.
  • two cylinder bores 2 are formed in each of the inner and outer calipers 1a, 1b.
  • this invention is also equally applicable to opposed-piston type disk brakes having more than two cylinder bores in each of the inner and outer calipers, opposed-piston type disk brakes having one cylinder bore in one of the inner and outer calipers, and floating type disk brakes in which a plurality of cylinder bores are formed in only the inner caliper.
  • the pipe arrangement of the present invention is also applicable to a fluid passage in a fluid pressure system of an antilock brake system.
  • the present invention is applicable to any cast hydraulic unit having fluid passages in the form of straight or arcuate pipes that tend to shift axially due to poor bonding or due to the pipes not being bonded on purpose. That is, by providing engaging portions extending in a diametric direction of the pipes, it is possible to easily and reliably prevent axial shift or dropout of the pipes.
